A.caddy full of tubes are coming my way.

One tube immediately stuck out to me- that 20LF6- if it IS a good, new-old-stock (unused) tube- that tube could be worth a Ben Franklin all by itself.

Gordon.
 
I've got a set of 6lr8 in the mail. Same as the 6lu8, there is a thread on here somewhere for those. Its basically half a 12at7 and a 6973 in one bottle. Planning a push pull build but they make a perfectly fine SE amp. It would be similar to a 6v6 SE but allows higher plate voltage. Figure about 5 watts in pentode mode if run close to datasheet spec
I really ljke the 6LR8 SEUL amp I built. There is another one just like the 6LR8, but has an anode cap instead of it connecting to a pin. I almost went with that one. I still could if I added a couple jacks to connect a wire to the anode caps.
 
Those 6HA5's are used in some Fisher FM tuners and receivers. But nobody around here likes that stuff ;)
I really need to re-tube my Dynaco FM3 tuner. I'll have to see if there are any I need in that caddy. I saw a few odd ball rectifiers too in that mess of tubes.

When we bought our house in 2020, the PO left A LOT of crap for us. Some of that was 3 or 4 boxes of tubes, and a really nice caddy. I knew most of the tubes were spent TV type, but I was psyched about the caddy. She called a month after we moved in and asked for the caddy back--it was her dad's, etc. She did say I could keep any tubes I wanted. I got a handful of nice preamp tubes, and a pair of NOS 1L6 tubes! I just happen to have a Zenith Transoceanic, which was the only radio to use the 1L6.
 
Those boxes look to be in good shape. I have spent hundreds of dollars on new tube boxes, to put all the bulk tube buys that I have acquired. New boxes can be a buck a piece. Just get some small avery labels or use your brothers to make labels those boxes can be reproposed.

I plan on keeping the tube boxes. I always keep any boxes from tubes I buy and use too. I'll need some of those old TV tube boxes for.loose.tubes that I have that won't fit in the boxes I do have on hand.
 
Tube caddys are useful even if the contents is less so. Its a cool vintage piece too. I've ended up with several, I think two GE, an RCA, a very beat Zenith, and a fairly rough Westinghouse one. One of the GE has a tube pin straightener on it.
 
Out of all those tubes just a few are useful. Five 6GH8A's, one 6LR8, one
6AQ5A, one 6EM7 dual triode, one 6LX6, and one 6LR6. The 6EM7 dual triode I've seen used in headpbone amp builds. All look to be new but I'll test them to be sure.
Most of the tubes in this caddy were Lindal branded made in Japan.

Even back in the mid 2000's, if you bought a lot of mixed tubes, you'd get 90% TV pulls. People sifted out all the Hi-Fi and guitar amp ones — even back then — and sold them individually on eBay.

Well, I guess those 6GH8 can be used in some ST70 boards. :thumbsup:
 
Most of the time when I thought I got a score in a pile of tubes, it turned out to be dead or at least fairly weak. Box of old radio tubes had a half dozen 45's. I think 4 work, none of them show over 40%. Probably adequate for an old radio but not much else. The 50 that was in there is dead.

Ya, four of the 6GBH8's are Sylvania and look like they've never been used. The 5th one is that Japanese brand like most of the tubes are. I wonder if that Lindal brand just rebranded tubes from western brands, or had the few Japanese brands that made tubes make them?
I did find a few tubes that were used but most I think are new.
I found out the yard sale these came from is an on going thing on the weekends for some local charity. The guy told my son he had a bunch more tubes. My son is going to check next weekend.
